Annual market size of NFT in different segments worldwide 2018-2021

The numbers shown refer to sales volume, meaning NFT sales between a buyer and seller. The source mentions these figures do not include transactions made within the NFTs themselves, like financial transactions within NFT games. Sales volume and in-game transactions combined are referred to as "traded volume".

The numbers provided were rounded.

The source defines the segments as following:

• Art: Marketplace, project or individual artist who produces, sells or generates content in the form of an NFT which is considered to be a work of art or relates directly to an art form whether manual or generative;
• Collectibles: Project whose primary function is to issue tokens intended to be collected. These tokens can be part of a system that includes gamification or a set of interactions between collectibles themselves or between the collectors and players;
• Gaming: Video game using the NFT standard. This can be Trading Card Games (TCG), strategy role-playing games (RPG) or any other fun-based gaming experience incorporating NFT;
• Metaverses: Parallel digital universes which offer a set of unique experiences to users. These virtual worlds are accessible via a computer, virtual reality headset, or even a smartphone. They can be compared to the experiences offered by Virtual World Second Life and more recently to the film Ready Player One;
• Utilities: Covering a wide variety of projects in which the NFT itself does not necessarily have a gaming or artistic function. Among other use cases utilities can be NFT domain names, tickets and assets that can grant access or specific rights to their owner;
